Mexican Trucks

California Highway Patrol commercial vechicle inspector Ruben Montanez inspects the undercarriage of a truck entering the U.S. from Mexico at the CHP's Otay Mesa Inspection Station Thursday, Sept. 6, 2007 in San Diego. Dozens of protestors waved signs and American flags at the border crossing Thursday to protest a program that will allow up to 100 Mexican trucking companies to freely haul their cargo anywhere in the United States.
